Hi all,
This set contains a small fix for the omap3isp crashing the system, as
well as cleanups for the smiapp driver.
Sakari Ailus (7):
omap3isp: Prevent enabling CCDC when stopping streaming
smiapp: Simplify condition for choosing 8-bit access
smiapp: Use unaligned get and put functions
smiapp: Turn limit lookup into a function
smiapp: Move SMIA limit reading up
smiapp: Refactor reading SMIA limits
smiapp: Move definitions under driver directory
